NAS HDD Showdown: WD Red vs. Seagate NAS

We've wanted to put these two drives together for a showdown ever since Seagate announced its NAS hard drive that competes with WD's Red NAS drive.

Benchmarks - 4 HDD / RAID 5


RAID 5: Use block-level striping with parity data distributed across all member disks.

This series of tests show single user performance with I/O coming and going to one PC. We configured the Thecus N6850 with an EXT4 file system, HDD sleep off and used a 10GbE Intel X520-SR2 to an Extreme Networks 400-48T. The client PC then connected to the Extreme Networks 400-48T switch.


The Seagate NAS 4TB outperformed the WD Red 4TB in every single user test with NASPT.
